Assessment of radiation protection and safety management at Hongyanhe Nuclear Power Plant (2012-2021)
This paper introduces the radiation protection safety management system of Hongyanhe Nuclear Power Plant, and presents the statistical results of the individual dose report of the nuclear power plant from 2012 to 2021. Analysis and evaluation on the proportion of collective dose for overhauls and the main population as well as job types receiving collective dose were conducted. Important anomalies relat-ed to radiation protection management and the causes were analyzed. The results showed that the control of occupational exposure dose of Hongyanhe nuclear power plant met the national standards while operat-ing safely and stably. Contractors contribute the most part of collective dose radiation exposure. The lar-gest contribution to the collective dose comes from overhaul, mechanical maintenance, main insulation maintenance, ect. Radiation protection management should focus on relevant activities during the over-haul and contractors management.
